REFRIGERATOR DRAIN.

My invention relates to improvements in draining means for refrigeratorsand the like. It is particularly designed to provlde a drain for tubularreceptacles which are ada ted to contain liquid.

y invention is especially adapted for use in connection with that typeof bottle cooling refrigerator wherein the bottles are passed throughsubstantially U shaped tubular channels for cooling purposes. In thistype of refrigerator there is usually provided an outer corrugated tuband an inner corrugating tub nesting the outer tub, the walls of the twotubs being spaced apart to form substantially tubular channels throughwhich the bottles to be cooled are adapted to be passed. The spacebetween the channels is adapted to be filled with a cooling liquid andthe inner tub is adapted to contain ice or other refrigerating medium.The drain of my invention is especially applicable to this type ofrefrigerator as it permits of the normal draining of the inner tub whenthe water therein attains a predetermined level and at the same timepermits of the comlete draining of both compartments when esired.

For the pur ose of disclosing my invention I have illustrated one'embodiment thereof in the accompanying drawings in which Fig. 1 is a.perspective view partial] in section of a type 0 refrigerator with whichmy invention may be used;

Fig. 2 is a detail section of a part of the refrigerator and of thedrain, and Fig. 3 is a detail partial sectional view showing the drainopened for complete drainage. V

The refrigerator of the type illustrated comprises a suitable receptacleor casing 1 in which is mounted a corru ated tub 2 U shaped in crosssection, a. suitable filler of insulating material being interposedbetween the tub and the walls of the casing. Suitably supported innesting position and spaced apart from the tub 2 is an inner corrugatedtub 3 substantially U shaped in cross section. This arrangement rovidesa series of water communicating tu ular channels 4 through which thebottles to be cooled may ass. Both tubs are open at their tops. oorssuch as 5 are provided for closing the openings to the channels 4 and acover plate such as 6 is provided for covering the Application filedMarch 11, 1926.

inner tub. This inner tub chamber 7.

For drainage purposes the outer tub 2 is provided with an opening 8through which projects .a drainage tube 9 the upper end of which liesadjacent to the inner tub 3 immediately beneath an opening 10 therein.The tube 9 is provided with an annular flange 11 on which the bottom ofthe outer tub 2 seats and has an extended nipple 12 interiorly screwthreaded for connection with a. drain pipe or suitable drain cock 13.This tube 9 is provided in its sides with drain openings 14 whichcommunicate with the space between the outer and inner tubs. The upperend of the tube 9 preferably has a permanent connection with the bottomof the inner tub 3 and at the annular flange 11 with the bottom of theouter tub 2. This arran ment provides for a drain communicating bothwith the chamber 7 in the inner tub 3 and with the chamber 4 between theouter and inner tubs 2 and 3.

In normal use of the refrigerator the water in the chambers or tubes 4is maintained therein. The ice is placed in the inner chamber 7 and asthe ice melts it is desirable to have some means for drainin the waterfrom this chamber after it reac es a predetermined level. To this end Iprovide a drain pipe 15 which projects into the drain tube 9 and has ascrew threaded end 16 taking into the internal screw threads 17 in thelower end of the tube 9. This drain pipe 15.has an annular collar orflange 18 backed by a. collar 19 which flange 18 bears on the innersurface of the inner tub 3 so that when the pipe 15 is screwed down intothe tube 9 the inner tub is clamped between the top of the tube 9 andthe flange 18. Drain openings 20 are formed at a predetermined pointnear the top of the drain pipe 15 throu h which the water from themelting ice of t e chamber 7 drains and above these openings there isalso provided openings 21 into which a turning pin may be inserted forrotating the pi to screw it into and out of its socket. It will be notedthat this arrangement provides provides an ice a means for normallydraining the inner tub and at the same time when it is desired to emptyboth the inner tub and the space be- 4 tween the inner and outer tubs itis merely necessary to remove the pipe 15 when the water will flowthrough the drain tube 9 from both chambers.

I claim as my invention:

1. The combination with a pair of nested tubs each arranged to containliquid, a drainage tube connected with the bottom of the inner tub andarranged to extend through the bottom of the outer tub and havingopenings communicatin with the outer tub a second drainage tutelescoping said first mentioned tube, and removably threaded therein toclose said first mentioned tube and arranged to extend upwardly into theinner' tub for drainin the inner tub and having means for closing thedrainage connection of the first tube with the inner 2. The combinationwith a pair of nested tube each adapted to contain liquid, of a drainatube projecting through the outer tub an having its inner end bearing onthe inner tub, an annular flange on said tube on gthe outer tub, asecond drainage tu telescopically screw threaded into said firstmentioned tube and projecting into the inner tub and an annular flangeon said tube bearin u n the inner surface of the inner tub w are whensaid tube is in position the wall of the inner tub will be clampedbetween the end of the first mentioned tube and the collar on saidsecond mentioned tube.

3. The combination with a plurality of nested tube, of a drain thereforcomprising a draining tube having a drainage connection with the bottomsof each of said tubs, of an overflow drain tube associated with saidfirst mentioned tube, said overflow tube co-operating with the firstmentioned tube when in drainage position to establish an overflowpassage from'the inner tub and to close the drainage connections of thefirst 4t mentioned tube with both tubs, and movable to a position tosimultaneously establish drainage connection between both tubs and saidfirst tube.

4. The combination with a pluralitypf nested tubs, of a drain tubecommon to all tive tubs, said drainage tube being movable to a positionto establish simultaneous 55 drainage communication between the firsttube and both-tubs.

5. The combination with a plurality of nested tubs, of a drainage tubecommon to all of the tubs and having'a drainage connection with each ofthe tubs, of a'second drainage tube telescopically insertable in saidfirst draina' e tube and having means for closing the rainageconnections of the first mentioned tubes with each of the tubs and forestablishing an independent drainage connection for the inner tub, saidsecond mentioned tube being removable from position to permit thedrainage of both tubs through said first mentioned tube.
